Bananas ripening is a chemical change. First, there is a change in color of peel from green to yellow then to brown. Second, there is a change in taste. You will notice a change in taste as the bananas ripen. They become sweeter and sweeter as they begin to ripen.

Devise a temperature scale, abbreviated g, for which the magnitude of the ideal gas constant is 1.00 j g–1 mol–1 .

The value of ideal gas constant (R) in Joule is 8.314 Joule $Kelvin^{-1}$ $mol^{-1}$ . Now the given expression is 1.00 J. g $g^{-1}.mole^{-1}$ . Where the g represent the temperature. Thus the abbreviated g must have the value 8.314 to satisfy the original value. Thus the temperature scale will be 1 kelvin = 8.314 g. Now 1 kelvin = -272.15°C or in terms of abbreviation of g we can write -272.15 °C = 8.314g, or, 1°C = (-) $\frac{8.314}{272.15}=0.030$ g. Thus the temperature scale of the g scale is 1 kelvin (K) = 8.314g and 1°C = 0.030 g.
